Sodium formate

Product Overview

Sodium formate is a multifunctional organic acid salt that combines reducing and buffering properties; it is also known as sodium methanoate, with the chemical formula HCOONa, and serves as an important basic chemical raw material. Owing to its unique chemical characteristics, it plays an irreplaceable role in various fields such as environmentally friendly snow melting, leather tanning, textile dyeing and printing, and chemical synthesis. It not only meets the differentiated functional needs of different industries but also aligns with the trend of green chemical development.

Technical Principle

The core technical principle of sodium formate is based on its three key chemical properties: First, its reducing property allows it to be oxidized into sodium carbonate, making it suitable as a reducing agent in dyeing and precious metal recovery processes to facilitate specific chemical reactions; second, its buffering capacity gives its aqueous solution a weakly alkaline nature—with a pH value between 7.5 and 8.5 for a 10% solution—effectively maintaining stable acidity and alkalinity in reaction systems and preventing fluctuations in pH from affecting reaction outcomes; third, its environmentally friendly degradability makes it an ideal alternative to traditional chloride-based de-icing agents. The product is biodegradable, with a BOD₅/COD ratio greater than 0.5, thus avoiding long-term environmental burdens. Additionally, at high temperatures, sodium formate decomposes into sodium oxalate and hydrogen gas, which further generates sodium carbonate, expanding its application scope in chemical synthesis.
